SGS INTRON has been selected by Rijkswaterstaat of the Dutch Ministry of Infrastructure and the Environment as one of the four chosen companies in road construction services to develop an ultra-quiet road surface.
This innovative, four-phase project began on 20 January 2014 and is scheduled to be completed with an implementable ultra-quiet road surface in 2016. 

The Client: Rijkswaterstaat

Part of the Dutch Ministry of Infrastructure and the Environment, Rijkswaterstaat 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. 

SGS INTRON & PERSISSST Add Value to Rijkswaterstaat Project

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.
In the Netherlands, 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. 

SGS INTRON Road Construction Services

In January 2010, SGS acquired INTRON Holding BV, a leading global benchmark in the construction industry. SGS INTRON offers tailored solutions for road construction to diverse clients including governments, designers, contractors and raw materials suppliers. Independent and unbiased, SGS INTRON provides impartial third-party services during road construction. Expert personnel, state-of-the-art technology and a professional laboratory for the testing of building materials make SGS INTRON a forerunner in the advancement of road construction. SGS INTRON has participated in the development of several new road products such as rollpave and silent joints.
Transport and mobility are key in society today, underscoring the need for durable and safe roads. Inferior roads present dangers to freight carriers, commuters and the surrounding environment and demand regular repair which increases maintenance costs. The construction and maintenance of strong and durable roads is difficult due to surfaces being exposed to changing and extreme conditions and the fact that the quality of road product components varies widely.
SGS INTRON experience and expertise in testing and assessing the performance and durability of road materials and products provide the understanding of road materials behaviors in relation to expected loads and deterioration mechanisms. Services for road construction include assessment and improvement of asphalt properties, the determination of asphalt component quality and suitability, calculations of the CO2 footprints of semi-heated asphalts and the assessment of damage to overheated asphalt. SGS INTRON tests bitumen, including composition PAH and rheology/viscosity in state-of-the-art laboratories. Expansion joints are assessed and tested and service life predictions are made. SGS INTRON road construction experts determine the maintenance condition of existing roads, draw up subsequent plans for maintenance and repair, control road mixture designs and audit and inspect the application of road products. SGS INTRON is deeply involved in the development of new road products including rollpave and road materials.
SGS INTRON is proud to take part in this unique project and looks forward to working with all the partners to improve the quality and safety of roads for the citizens of the Netherlands.
