Experience
Since joining BRE in 1995, Mr. Martin has been involved in the research of pavement design and performance. He has been responsible for supervising and conducting the evaluation and/or design of numerous pavement projects. Mr. Martin has been responsible for numerous structural evaluations of pavements including highways (i.e. Oklahoma and Texas), city streets (i.e. Austin, Texas, Leander, Texas, Trophy Club, Texas), airfields (i.e. Houston Hobby, Houston Intercontinental, Corpus Christi International, Dallas Ft. Worth Airport), and port facilities. These analyses range from projections of remaining life to design of rehabilitation alternatives and pavement management services.

As a project engineer for the collection of pavement distress data for the Texas Department of Transportation (TxDOT), Mr. Martin was responsible for the data collection of over 4,000 roadbed miles of pavement surveys. Similarly, Mr. Martin has been certified in the Federal Highway Administration (FHWA) Pavement Distress Identification System and has conducted over 500 surveys for the FHWA. He has also evaluated over 500 lane miles of pavement in various cities (i.e. Austin, Texas, Cedar Park, Texas, and Trophy Club, Texas) using ASTM D 5340-93 and ASTM E 1778-97. The data was used in the implementation of the MicroPAVER pavement management software using ASTM E 1889-97 and E 1166-91.

Some of the research studies have included hot mix asphalt concrete incorporating Sulfur-Extended Asphalt (SEA) and the effects of different crude sources on pavement performance. Mr. Martin has also been involved in several National Cooperative Highway Research Program (NCHRP) studies. NCHRP 1-32 involved the development of a Pavement Design Catalog using the AASHTO procedures and elastic layer theory with state pavement design criteria. NCHRP 1-34 studied the Performance of Subsurface Pavement Drainage.

As Co-Principal for the FHWA/LTPP Southern Region Coordination Office, he also served as distress coordinator and managed the identification, selection, verification and monitoring of test sections for study under the LTPP program. As part of this responsibility, Mr. Martin conducts quality assurance on all data related to these LTPP test sections, including materials data, roughness measurements, visual distress, traffic, friction, maintenance and rehabilitation data.

Prior to joining BRE in 1995, Mr. Martin was previously employed by DeShazo, Tang & Associates in Dallas, Texas. His responsibilities included hydrological analysis and design, pavement analysis and design and traffic analysis. He also worked on the preparation of traffic impact studies involving the collection and usage of zoning maps, thoroughfare plans, traffic volumes, turning movement counts and lane geometry. Mr. Martin was involved in the Congestion Mitigation and Air Quality (CMAQ) signal warrant study. He developed information systems and utilized data to serve North Central Texas County of Governments (NCTCOG) in determining intersections that were qualified for improvement to reduce emissions.
