Pavement Stabilisation – Harap Panjang

Pavement stabilisation is a treatment to increase the bearing capacity of pavements layer component by improving the properties and technical characteristic of materials. Both improvement is done by mixing the material with a suitable binder in sufficient water content then continued with a series of compaction process. Further value engineering of pavement stabilization are:

Improve bearing capacity of pavement material
Reduce compresability and plasticity of subgrade material
Improve characteristic and resistance of waterproofing
Improve durability of pavement material.

Compared with the conventional method, pavement stabilisation process is generally offers construction time savings and one of sustainable solutions. In addition to proper construction equipment and operational methods, engineering process is a fundamental factors to achieve success of the pavement stabilization. Please contact to our engineering staff (arif@harappanjang.com) to get engineering advice, discuss in developing pavement investigation and also both mix and structural pavement design.

PT. Harap Panjang has been involving the pavement construction and rehabilitation using stabilisation technique of more than 400 km of single lane carriageway in both government (Bina Marga) and industrial roads through Riau Province, Indonesia. This method is suitable for road rehabilitation, considering to the lack of qualified aggregate in the regions . The standard aggregate shall be imported for subbase and base material by barge from nieghbouring island, Karimun. But, the existing pavement material which will be improved are suitable if stabilised with both cement and lime. With stabilization technology, the Client can save the cost of between 30% to 50% compared with the conventional method, in addition to faster construction, reduce traffic disruption and environment friendly. As an example of the benefits of using stabilization techniques in road improvement and road rehabilitation, please read the Worldhighways Magazine, link of website attacheds.
