Use of LTPP Data to Quantify Moisture Damage under Crack Sealing and Surface Treatments in Asphalt Pavements [PDF]
MATEC Web of Conferences, 2019 Crack sealing and seal coats are used to prevent the ingress of water into the pavement, thus delaying its deterioration. Yet, earlier studies indicated that sealing pavements in areas with high ground water table (GWT) prevented moisture from escaping ...

Research on Maintenance Management of Flexible Pavement Based on C-LTPP
IOP Conference Series: Earth and Environmental Science, 2021 Abstract Based on the Canadian Long-Term Pavement Performance (C-LTPP) data, this paper chooses the road performance related data as variable factors. According to the Dipstick detection results, the characteristic values such as rut depth, wheel track width and cross section area are extracted to describe the rutting.

THE ANALISYS OF RUTTING OF THE LTPP PROGRAM IN THE UNITED STATES
JOURNAL OF PAVEMENT ENGINEERING, JSCE, 2000 Since 1987, theLTPP (Long Term PavementPerformance ) program had been implemented in theUSaspartofthe SHRP (Strategic Highway Research Program ). After the termination of the SHRP in 1992, the FHWA (Federal Highway Administration) continued the research and collection of data on the LTPP program, as this program isa 20-year-term plan.

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.This study systematically investigates the influence of various material and soil property inputs on the mechanistic‐empirical (ME) design of flexible pavements, utilizing the AASHTOWare Pavement ME Design software. An experimental design framework, specifically the Plackett–Burman design, was employed to analyze the effects of eleven critical ...
