【 摘 要 】

Due to increased traffic volume and conventional pavement designs with poorer subgrades under tropical environment and conditions, most roads are relatively over-loading and the repair or maintenance works to existing pavements become a focus. A super-fast and super-strong technology is required to strengthen the existing pavements in short period with lesser disturbances to both public traffic and operations. Chemical in-situ rehabilitation has become the trend of quick repairs in Malaysia. Chemilink systems have more than 25 years track records in tropical region, its product has been officially approved by Federal Jabatan Kerja Raya (JKR) and Lembaga Lebuhraya Malaysia (LLM) since 2016 in JKR Material List (JMAL). This rehabilitation method can strengthen various pavement base/sub-base courses and achieve higher performances, such as California Bearing Ratio(CBR) values with more than 120% within 24 hours, it also become more popular for pavement upgrading/strengthening and maintenance in airfield and seaport too. It significantly increase overall performances and durability of various pavements with higher technical parameters, faster construction, longer working life and finally overall cost effectiveness. It can utilize the in-situ and local materials in green and sustainable manner. The application procedure include site investigation, mix-design, rehabilitation process, and immediate and long-term performances.
