Abstract:Two sections of Interstate 10 have been selected for study to determine the initial roughness and subsequent change in roughness with time. The two sections represent different design and construction procedures.
Section 1 is located on I-10 between LaPlace and Kenner and is approximately 12 miles in length. This section was constructed with precast prestressed monolithic girder spans resting on precast caps with 54 inch precast prestressed piles. Eight one mile segments were selected for measurements with four being on the eastbound roadway and four being on the westbound roadway. All measurements are taken in the outside lane only.
Section 2 is located on I-10 between Henderson and Grosse Tete and is approximately 18 miles in length. This section was constructed with precast prestressed monolithic girder spans made continuous through four 70 foot spans by 12 feet slab sections poured in place and resting on precast caps with 54 inch precast prestressed piles. Four one mile segments were selected for testing with two segments on the eastbound roadway and two on the westbound roadway. All measurements are taken in the outside lane only.
