THE use of new methods for road pavement is expected to reduce maintenance costs by up to 30%, says Deputy Works Minister Datuk Rosnah Abdul Rashid Shirlin.
She said the new methods, such as “cup-lump modified asphalt” (CMA), “cold in place recycling” (CIPR) and “polymer modified asphalt” (PMA) had yielded good results and improved road quality.
“These new methods are among the efforts made by the ministry to improve the quality of roads in the country, including in Sabah, and reduce maintenance costs compared to existing conventional methods,” she told Datuk Juslie Ajirol (BN-Libaran), who asked her on measures taken to improve the condition of Sabah’s main roads.
Replying to Juslie’s supplementary question on monitoring safety of roads which involved hazardous and risky slopes, Rosnah said the ministry had produced a slope hazard and risk map where data on the roads and slopes was classified according to high, medium and low categories.
“We are also implementing ‘slope mapping’,” she said. — Bernama
