SGS INTRON Develops Ultra-Quiet Road Surface: PERSISSST in the Netherlands

SGS INTRON was awarded a contract to develop an ultra-quiet road surface in the Netherlands.

Online PR News – 18-February-2014 – 18.02.2014 – As one of the four chosen companies in road construction services, SGS INTRON has been selected by Rijkswaterstaat of the Dutch Ministry of Infrastructure and the Environment to develop an ultra-quiet road surface. Started on 20 January 2014, this innovative, four-phase project is scheduled to be completed with an implementable ultra-quiet road surface in 2016.


Rijkswaterstaat, part of the Dutch Ministry of Infrastructure and the Environment, is responsible for the design, construction, management and maintenance of the main infrastructure facilities in the Netherlands. These elements include the main road and waterway networks as well as the principal water systems.


One of four road construction ( market leaders participating in the first phase of this innovative project to develop a quiet road surface, SGS INTRON boasts six years of experience in modeling mechanical and acoustic road surface properties and testing products. This extensive experience has resulted in SGS INTRON being part of the first phase of PERSISSST; the development of a prototype for an ultra-quiet road surface. With a life span of at least 7 years, this new poroelastic road surface (P.E.R.S.) will lower noise levels by 10 decibels reducing the need for expensive noise abatement measures such as sound barriers, sunken roads and road canopies.

SGS INTRON provides Rijkswaterstaat comprehensive services, expert personnel, state-of-the-art testing facilities and tailored solutions, improving asset performance, protecting investment and increasing asset value.
