Frequently Asked Questions About Pavement Friction Assessment
What are your pavement friction assessment methods?
We utilize state-of-the-art technology such as the Sarsys-ASFT T2Go continuous friction tester and the ELAtextur laser macrotexture scanner to measure pavement friction and texture accurately. Our methods are designed to provide comprehensive data on roadway, sidewalk, and pathway surfaces.
How does the pavement texture consulting process work?
Our process begins with an initial consultation to understand your needs and site conditions. We then conduct field testing to gather data on surface texture and friction levels, analyze the results, and provide you with detailed insights and recommendations.
What is the timeline for receiving results after testing?
Once the field testing is complete, you can expect to receive a comprehensive report within 5 business days depending on the size of the project. This report will detail the findings and include actionable recommendations for improving surface performance.
Do you offer customized solutions based on specific project requirements?
Yes, we pride ourselves on delivering tailored solutions to fit the unique needs of each client. Whether you’re addressing specific safety concerns or regulatory requirements, we can adapt our services to meet your project goals. Recommendations for cost-effective surface restoration treatments are a particular strength of GoodGrip.
What are your pricing options for pavement friction testing services?
Our pricing is based on the scope of the project, including the size of the area to be tested and the specific services required. Contact us for a detailed quote tailored to your project needs.
Do you provide ongoing support after testing is completed?
Absolutely. Our team is available for follow-up consultations to discuss the results, provide further recommendations, and assist with implementation. We are committed to ensuring the safety and performance of your surfaces.
What measures do you take to guarantee the accuracy of your testing?
We ensure the accuracy of our testing through calibrated equipment, standardized procedures and methods, and experienced personnel who follow industry best practices. Our focus on precision and quality is paramount.
How can I schedule a consultation with your team?
You can easily schedule a consultation by reaching out through our contact form, calling us directly, or sending an email. We will get back to you promptly to discuss your project.
What is pavement texture and why is it important for safety?
Pavement texture refers to the surface characteristics of the pavement material, including its roughness, pattern, and the aggregate size used in the mixture. It plays a crucial role in driving safety by influencing tire grip, water drainage, and vehicle handling. A well-textured pavement reduces the risk of skidding, enhances wet weather performance, and prolongs the lifespan of the roadway. Understanding and assessing pavement texture helps engineers and transportation agencies maintain optimal road conditions and improve overall road safety.
Are road agencies responsible for providing adequate friction on their roadways?
Yes. Road agencies in Canada are required to maintain their roads in a safe and passable condition, which by extension includes the provision of adequate friction.
What are some of the surface restoration techniques and treatments if friction or texture is low?
The most appropriate surface restoration technique(s) depend on why the friction or texture is low. GoodGrip can assess the surface condition and make surface restoration recommendations, including surface treatments such as chip seal, slurry seal, micro-surfacing, bonded wearing course, or overlay. Removing contaminants such as excess asphalt cement can be completed using micro-milling or hydro-blasting while polished aggregates can be treated with shot-blasting. Increased macrotexture can be imparted with diamond grinding and micro-milling.
Are there minimum recommended levels of pavement friction?
Yes. In 2023, the US Federal Highway Administration (FHWA) issued Report SA-23-006 (CHARACTERIZING ROAD SAFETY PERFORMANCE USING PAVEMENT FRICTION) that includes minimum investigatory levels for pavement friction (see Table 13). These levels were determined based on a comprehensive analysis of the relationship between pavement friction and accident rate. Maintaining pavement friction at or above these recommended levels greatly reduces the rate of accidents, thereby reducing the frequency and severof property damage, injuries, and fatalities.
