The guardrail is mainly to follow the AASHTO M180, GB-T 31439.1-2015 and EN1317 standard. The requirement that needs to be met is 3-20 seeing as the building is about 20 ft set back from the bollard. a tree some distance further from the road). Posts can be divided into ordinary steel posts and flange posts. These new guardrails, which are over 20 metres in length, were recently installed on the slip road near the start of the Bukit Timah Expressway (BKE) towards Woodlands. Construction Standards . In this study, validated vehicle and W-beam guardrail models installed behind AASHTO Type B curbs were used to perform full-scale simulations of vehicle-curb-guardrail impacts. While curbs main functions are to separate the road from roadside, control vehicle rights-of-way, and channel water runoff; their use is discouraged by AASHTO from being installed on high-speed roadways due to the disruptive behavior caused when vehicles strike them. (BCA Registered Contractor) Contact Us. For the thickness of the guardrail mainly through the 2.67mm to 4.0mm. This system has been theorised to help prevent subsequent rear-end collisions from other vehicles.

These impact protection materials are meant for high-speed transport environments or locations where heavy loads are moved or transported, such as warehouses, construction halls and airports. Sources put the cost of installing a metre of the guardrail system between US$300 (S$414) and US$400 (S$553). A barrier should only be installed when the consequences of vehicle impact with the barrier is likely to be less severe than the consequences of impact with the feature being shielded. It can be customized according to customer’s requirement. Roadway design, including the use of traffic barriers, is a critical aspect in transportation safety and is used to reduce the severity and frequency of automotive accidents. The ASTM standards vary from one of three options: 0-3ft, 3-20ft and 20-50ft. I forgot to mention that in my original post. AASHTO M180 w-beam guardrail is a kind of road crash barrier made as per M180 standard, used for securing highway safety by preventing errant vehicles from sliding out of the roads and impacting the roadside buildings or other objects.
