Parkhill Smith & Cooper, Inc. 4222 85`h St Lubbock, Texas 79423 Re: API Proposal for Pavement Evaluation of Runway 17R -35L, Lubbock, Texas. Dear Mr. Haberer: All About Pavements, Inc. (API) appreciates the opportunity to submit our proposal to Parkhill, Smith and Cooper, Inc. (PSC) to assist in the evaluation of Runway 17R -35L. As we discussed, our attached scope of work includes nondestructive deflection testing (NDT), a site visit to the airport to conduct a visual survey of the pavements, and assistance in the preparation and evaluation of results from geotechnical and laboratory testing. In addition, API will evaluate the results and work with the PSC and the Airport to develop feasible rehabilitation strategies and pavement designs. Final and draft reports will be prepared to summarize the results from this study. API proposes to conduct our work for a lump sum amount of $61,214.. Should you have any questions, please do not hesitate to call me at 217-586-2765. Sincerely, All About Pavements, Inc. Wayne J. Seiler, Ph.D., P.E. Project Manager Enclosure 1. Scope of Work 2. Fee Proposal Pavement Management — Evaluation —Testing — Design RW 17R -35L Evaluation LUBBOCK PRESTON SMITH INTERNATIONAL AIRPORT (LBB) Runway 17R -35L Pavement Evaluation Scope of Work October 7, 2011 PROJECT UNDERSTANDING RW 17R -35L is an old military runway that was constructed in 1976 and has material -related distresses (MRD). The keel section was reconstructed in 1976 and is in better condition than the outboard sections of the runway. The runway has been 'inspected using the Pavement Condition Index and MicroPAVER. The keel is currently in "Good" condition and the outboard sections are in "Poor" to "Very Poor" condition. The current cross section consists of keel is variable but primarily consists of 14 inches of jointed Portland Cement Concrete (PCC) and an 8 -inch P201 base, which is constructed on a 4 -inch P401 Asphalt Concrete (AC) layer and a P209 granular base. The Federal Aviation Administration (FAA) and the LBB Airport Authority were to evaluate the runway to determine the best rehabilitation strategy for Runway 17R -35L, the primary runway at the Airport. However, before any strategy can be implemented, it is important to conduct a pavement evaluation and preliminary engineering report (PER) that answers the fallowing questions: ➢ How much has the ASR deterioration progressed in the outboard pavements sections, where the presence of ASR has been identified? ➢ Has the ASR distress reduced the flexural and compressive strength of the PCG? ' If there has been a decrease in strength, has this decrease occurred throughout the typical PCC slab or has it been more pronounced at the edges and corners of the slab? ➢ If there has been a decrease in strength, how much variability in strength exists throughout the runway (e.g. keel, east outboard section, west outboard section, and north and south ends)? ➢ If there were no ASR distress, how much of the fatigue life of the runway (from repeated aircraft loads) has been consumed since the runway was opened? Has the amount of remaining fatigue life been reduced by ASR? Are the full -depth cracks in the keel on the runway primarily ASR related or fatigue related, or both? What is the projected rate of crack development that is expected to occur in the keel, east outboard section, and west outboard All About Pavements, Inc. (AFI) Page I RW 17R -35L Evaluation section within the next 1 to 14 years (e.g. When will the runway fail structurally?) ➢ Once this structural evaluation is complete, which repair strategy is preferred? To address these Questions, All About Pavements, Inc. (API) will accomplish the following pavement evaluation work as a subconsultant to Parkhill, Smith, and Cooper, Inc. (PSC) and accomplish the following objectives: A Conduct a Records Review. ➢ Conduct Nondestructive Deflection Testing (NDT). Based on the results of the NDT and a records review, assist PSC with the identification core and boring locations that will be extracted to conduct laboratory tests that will document extent and progression of ASR, changes in PCC strength, and cause(s) of cracking. ➢ Review laboratory test and geotechnical test results for RW 17R -35L. ➢ Identify the type and quantity of localized repairs that should be conducted in the short term on RW 17R -35L. ➢ Use the fleet mix and project aircraft annual operations to conduct structural evaluation work. ➢ Conduct a structural evaluation of RW 17R -35L to estimate the amount of fatigue life that has been consumed in the keel since it was originally constructed. ➢ Estimate the number of remaining years of life for the runway, incorporating the structural analysis results and the laboratory and geotechnical work that is conducted by another consultant under contract to PSC. ➢ Develop preliminary pavement designs for feasible intermediate and long term rehabilitation strategies. TECHNICAL APPROACH A detailed explanation of each task that expands on the project objectives is as follows: Task 1: Records Review Previous geotechnical and pavement evaluation and design studies will be reviewed by API. In addition, the following data is required to complete the study: ➢ Aggregate sources that were used to construct the runway )0- Material tests that were completed on the aggregates as part of the construction submittals or previous studies Previous average annual aircraft operations by aircraft type and model for the RW 17R complex A Projected average annual aircraft operations for the RW 17R complex All About Pavements, Inc. (API) Page 2 RW 17R -35L Evaluation API will also conduct a site visit to inspect the runway condition and map key distresses that exist on the runway keel and outboard sections. Tusk 2: Nondestructive Deflection Testing (NDT) The objectives of the NDT work on RW 17R -35L are as follows: ➢ Through center -slab testing, determine the extent and severity of structural deterioration that has occurred in the PCC layer from ASR and repeated aircraft traffic loads. The PCC elastic modulus and modulus of rupture will be determined throughout the runway. The mean values and the coefficient of variability will be evaluated to determine the relative condition of pavement areas throughout the runway and assist in determining the location of the cores. ➢ Through center -slab testing and joint testing, determine if the extent and severity of structural deterioration is more severe along the joints and corners of the slabs in each pavement area of the runway. ➢ Through transverse joint testing, determine if there has been a loss of joint load -transfer efficiency (LTE) since construction. A decrease in LTE will result in accelerated structural deterioration from fatigue due to aircraft traffic operations. A Determine the strength of the strength and stability of underlying base and subbase layers. ➢ Determine the subgrade elastic modulus values and the amount of variability throughout the runway. NDT will be conducted using a falling weight deflectometer (FWD), shown in Figure 1 and configured as shown in Figure 2. FWD tests will be conducted at 200 ft intervals on the runway. Four passes will be conducted on Runway 17R -35L at offsets of 12 and 62 ft from the runway centerline. At each test location, a PCC slab will be tested in the slab center and at transverse joints as shown in Figure 3. o Direction of Testing C) t Figure 1. Falling Weight Deflectometer. Figure 3.

Figure 2. Schematic of the FWD load plate and sensor configurations. The FWD will be operated by a trained operator who has extensive experience with airport operations and safety requirements. API will attempt to schedule the NDT work to coincide with other fieldwork to minimize down time of the runway. The FWD equipment that will be used by API can conduct the NDT work at night or during light rain, and does not require the use of any light carts. Task 3: Pavement Characterization In Task 3, the FWD data will be analyzed. The overall purpose of the data analysis is to assess the strength characteristics of the pavement layers and subgrade. The following parameters will be analyzed. Impulse Stiffness Modulus AN will analyze the maximum FWD deflection that occurs directly under the FWD load plate), in the center and transverse joints of PCC slabs, to identify pavement strength and assess the overall support conditions of the in-place pavements. In addition, the deflection occurring at the outermost sensor that is 72 inches from the load plate (Figure 2) will be used to obtain the overall strength of the subgrade. These deflections under the load plate and the 72 -inch geophone sensor are divided by the applied load (lbs) to obtain the Impulse Stiffness Modulus (ISM). Pavement ISM profile plots are helpful in identifying pavement design sections for long stretches of pavement. The maximum ISM values at the slab center will be compared to the maximum ISM values at the slab transverse joints to determine the severity of ASR, D -Cracking, and any other MRD that is located throughout Runway 17R -35L. Backcalculation of Pavement Layer Strengths A pavement layer strength analysis will be performed to identify the stiffness of PCC layers, the base layers, the granular subbase, and the underlying subgrade support. The pavement layer strength analysis will be performed using a technique called backcalculation. The backcalculated modulus values will be used to assist in the All About Pavements, Inc. (API) Page 4 RW 17R -35L Evaluation determination of the amount of structural deterioration in the pavement layers and the expected remaining life of the pavement. Task 4: Coring and Laboratory Test Plan The results that are obtained from an initial analysis of the NDT data and records review will be used to assist FSC in the final selection of core and boring locations that will be obtained during this study. Table 1 shows the number of cores that are proposed for the analysis work. Dynamic Cone Penetrometer (DCP) tests should be conducted at all boring locations. The DCP test results will provide subgrade strength data that will be correlated with NDT backcalculation results. In addition, the DCP tests will be used to determine if excessive moisture exists in the subgrade due to perched water or poor drainage conditions in the RW 17R -35L complex. Soil samples will be taken to conduct gradation analysis so that subgrade permeability can be assessed. Table 1: Recommended Boring Test Locations and Laboratory Tests.

Subgrade samples directly beneath the last unbound layer will be taken for gradation analysis and Atterberg Limits testing. Task 5: Traffic Analysis A traffic analysis will be completed for Runway 17R -35L to determine arrivals and departures at each runway end and at taxiway connectors. API will work with PSC to develop the fleet mix and operations that will be used for study. Task 6: Structural Evaluations A structural evaluation will be completed to estimate the amount of fatigue damage that has occurred since construction of the pavement facilities. NDT, laboratory test results, and aircraft traffic data will be used to determine what percentage of the fatigue life has All About Pavements, Inc. (APT) Page 5 RW 17R -35L Evaluation been consumed through 2011 and how many more years Runway 17R -35L can support projected future traffic operations. Task 7: Pavement Design API will review the previous studies data, current distress information, geotechnical results, laboratory test results, NDT analysis results, and traffic data to identify feasible pavement rehabilitation alternatives that address the functional and structural condition of the runway while considering aircraft operations and additional construction constraints that are identified by PSC and the Airport Authority. Preliminary pavement designs will be prepared using results from Tasks 1 through 6. Based on discussions of feasible rehabilitation options, designs will be completed using the FAA's AC 15015320-6E and FAARFIELD design software. Results will be checked with finite element analysis and the U.S. Army Corps of Engineer's PCASE design and analysis program. Task 8: Report Draft and final reports will be prepared that summarize the results from Tasks 1 through 7. Two copies of the draft report will be delivered to PSC and four copies of the final report. The final report will also include a DVD with photos of key distresses, NDT data, and PDF copies of the report and appendices. All About Pavements, Inc.

Scope: Perform a pavement and layer thickness survey along with a moisture survey at the Lubbock Airport in Lubbock, Texas: 1. 'Perform GPR testing on full-length of Runway 17R135L using a multi -channel towed array; • 11,500' x 150' collected on 2' spacing for comprehensive analysis; 2. Make observation for subsurface moisture inconsistencies; Radarview will calibrate GPR data to moisture findings in soil core samples collected and analyzed by Rodriguez Engineering; 3. Make observation of thickness of existing concrete pavement; • Radarview will calibrate GPR data using ground -truth from core samples collected and analyzed by Rodriguez Engineering; 4. Make observation for any non -typical structures under runway pavement within approximately 3 feet of the surface; 5. Confirm presence of dowel bars in joints; • Radarview will 3D image 10 percent of the joints to verify dowel depth and length with 3D models of reinforcing created. If needed, more 3D imaging can be performed on more joints. On the remaining joints, individual line scans will be performed for verification of dowel placement and depth, but not length; 6. Prepare formal report detailing the findings of the areas examined once all requested information is received from Rodriguez Engineering. 2. Fee: The fee to perform this comprehensive survey is $46,000.00, excluding any applicable taxes. This fee assumes the most comprehensive type of survey. The scope could be reduced and the detail reduced to affect the price by as much as 50 percent. 1. The fee covers all mobilization, materials, labor and report time; 2. Depending on the comprehensiveness of the requested analysis, time onsite can be anywhere from 3-7 days for data collection and an additional 10-16 days of analysis and reporting; 3. Delays out of Radarview LLC's control (i.e., weather, security, etc.) will be charged at a day rate of $1,800.00 per 8 -hour day or $225.00 per hour.
