【 摘 要 】
Pavement designs for roads have evolved from empirical approaches whose origins lie in AASHTO road trials in the 1950's. These are embodied in AASHTO guidelines from USA, the British Road note 29 and 31 as well as Arahan Teknik JKR guidelines. This approach constrains the designer and the contractor to use "standard" materials which were assumed in the empirical approach since these were the materials used in the trials. Any materials that are "nonstandard" cannot be utilised in the empirical approach. This leads to expensive pavement designs. With the development of mechanistic pavement design principles along with equipment to measure performance criteria such as stiffness, roughness, surface texture, friction etc performance-based pavement design and construction has become possible. This paper outlines the mechanistic approach with a case history of such pavement along with other important factors to be considered such as drainage of pavements which are essential for better pavement performance. Based on past successful history of performance-based pavement designs and construction there is a strong case that pavement designs can be done by mechanistic designs and the performance criteria be defined in specifications by way of roughness, stiffness, friction, surface texture in all road works contracts.
