About this file
This is a solicitation for the TX FTNP LAMR10(3) ALFL106(1), LAMR & ALFL Rehab of Roads & Parking project located at Lake Meredith National Park and Alibates Flint Quarries in northern Texas. The project involves rehabilitating approximately 7.75 miles of roadway across 6 sections of road, reconstructing approximately 0.25 miles of road, and rehabilitating 3 parking lots. Key work items include full depth reclamation of 140,000 square yards, asphalt concrete pavement, guardrail replacement, minor drainage improvements, and signing and striping. The purpose is to rehabilitate existing pavement at the end of its design life to improve safety and access for recreational users. The solicitation is broken into a base Schedule with 9 Options relating to specific roads and parking areas. Responses are due based on standard solicitation deadlines and procedures.

Memo To: Dan Lautzenheiser, PE
DJ&A
From: Jerry T Sayson, PE Date: May 20, 2021 Re: TX FTNP LAMR 10(3) & ALFL 106(1), Lake Meredith & Alibates Various Routes
BACKGROUND
This memorandum provides the geotechnical and pavement structural recommendations for the TX FTNP LAMR 10(3) & ALFL 106(1), Lake Meredith & Alibates Various Routes project (Terracon Project No. AR215033) which consists of improvements to the following roads;
LAMR-0010 83127 Sanford Yake Road 1.39 Miles LAMR-0100 83128 Fritch Fortress Road 1.34 miles LAMR-0101 83129 Blue West Access Road 1.39 Miles LAMR-0104 Harbor Bay 0.54 Miles LAMR-0103 83131 Bates Canyon Road 0.74 Miles LAMR-0106 104720 Alibates Access Road 2.35 Miles
Two NPS Repair and Rehabilitation projects are also included under this SOW, for repairs of to the following routes;
LAMR-0913 Sanford Yake Lower Parking Area 19,918 SF ALFL-0402 Unpaved Alibates Tour Road 0.23 Miles ALFL-0900 Trailhead Parking
0900A Harbor bay Parking A 3,054 SF 0900B Harbor bay Parking B 57,218 SF
The roads are used primarily for recreational purposes with the vast majority of the vehicles being passenger cars, pickups, and SUVs except for a few three axle service trucks.
RECOMMENDATIONS
Inspection of the slope at the lower Sanford Yake reveal minor erosion and can be improved by seeding and mulching the slope surface with Bonded Fiber Matrix and placing existing concrete barrier at the base of the slope to buttress the material.
DJ&A provided estimated traffic counts and was translated into Equivalent Single Axle Loads (ESAL). The traffic load utilized for pavement thickness design is 30,000 ESALs. Based on results
Responsive ■ Resourceful ■ Reliable 2 of pavement coring and soil borings performed at the project, the thickness of the existing asphalt pavements ranges from about 1 inch to 4.5 inches and the subgrade soils in the area consists of lean clays, silty sands and clayey sands (refer to attachment 1 Boring logs). Laboratory CBR tests indicates that the CBR value of the subgrade soils ranges from 4 to 5.3 (Refer to attachment 2 CBR Test Results). Utilizing the CBR value of 4 for the project translates to Subgrade Resilient Modulus (Mr) of 6200 psi used for flexible pavement design. The following additional design parameters were utilized for pavement engineering analyses based on AASHTO Guide for Deign of Pavement Structures (1993);
Level of Reliability 85% Flexible Standard Deviation 0.45 Rigid Standard Deviation 0.35 Flexible Initial PSI 4.2 Flexible Terminal PSI 2.0
CBR 6.0
Correlated Resilient Modulus, Mr 6200 psi Asphalt Concrete (AC) Layer Coefficient 0.44
For the Unpaved Alibates Tour road, the following minimum pavement thickness is recommended;
3-inches HMAC 6-inches Aggregate Base 6-inches Compacted Subgrade
For the repair and improvements of the various routes and parking areas, the following minimum pavement thickness is recommended;
3-inches HMAC 6-inches Full Depth Reclamation
A PG 64-22 binder should be used for the project’s asphalt concrete pavement. This binder is readily available and commonly used by Texas DOT.
Please let us know if you have any questions.
