The SP 64 Enables Very Fast Paving of High Quality Road Surfaces
Two important infrastructure projects in Thailand requiring the paving of new concrete roads are currently being realized with state-of-the-art slipform paving technology. Two different projects with many similarities. The advantages are clear: The construction process is faster, the quality of the paved surface is very good, and process reliability is consistently high. As no fixed molds are required, the manual labor required is significantly reduced.
Precision over a distance of 22.3 kilometers: Construction contractor Premium Concrete is realizing a road construction project with an overall length of 22.3 kilometers in Thailand’s Surat Thani province. The new section is a part of the important AH2 trunk road to Maluan.
“With the Wirtgen slipform paver, we achieve a high working speed and can simultaneously ensure high surface quality.”
Sirichot Phettong, Project Engineer at Premium Concrete
The slipform paver enabled the production of an extremely even, high quality concrete road surface.
The name Surat Thani means “The City of Good People”.
Optimized construction for heavy goods traffic: a further construction project is located between Tha Sala and Nopphitam on the section from Thai Bun to Nopphitam. The contractor CC Machinery & Construction Co. Ltd. is responsible for the upgrading of the 17-kilometer section of this important transport route.
As traffic drives on the left in Thailand, the left-hand lane tends to be used predominantly by heavy trucks. In view of this, it is being paved 3 cm thicker than the neighboring lane to cope with the additional stresses.
“We decided to use the slipform paver because Wirtgen offers outstanding customer care, comprehensive service, and training courses. These are particularly important criteria for us.”
Thawat Arunsuwannakon, Managing Director of CC Machinery & Construction Co., Ltd.
Both projects impressively demonstrate the outstanding performance of slipform pavers in contemporary road construction. The high paving speed, excellent surface evenness, and the long service life of the roads assure outstanding cost-effectiveness.
The projects set new standards for efficient concrete road construction in Thailand and are a decisive step forward in the realization of a sustainable transport infrastructure.
When using the inset slipform paving method, the concrete is placed directly in front of the machine and distributed by a spreading auger or spreading plow. The wet concrete is homogeneously consolidated by vibrators while the slipform mold defines the form and dimensions. The integrated dowel bar and tie bar inserter places the reinforcement exactly as required. The oscillating beam levels out smaller irregularities before the super smoother ensures a perfect surface finish.
