Road Marking Visibility & Safety Compliance Guide
Road Marking Visibility & Safety Compliance Guide

Are your road markings delivering the visibility you planned for?

Ensuring top-tier road safety is about more than just laying down fresh paint; it is about verifying that the paint performs when it matters most. For traffic engineers and contractors, confidence comes from hard data.

A retroreflectometer provides that proof. It measures how effectively a marking reflects light back to the source, quantifying night-time visibility by simulating a driver viewing the road ahead.

Here is how this instrument works and why it is the standard for professional assessment.

How to Do Superpave Mix Design: Step-by-Step Guide
How to Do Superpave Mix Design: Step-by-Step Guide

How to do superpave mix design - Superpave is a performance-based asphalt mix design system developed to improve pavement durability across varying climates and traffic conditions. Unlike older methods, Superpave is built to adapt. This method helps ensure your mix will stand up to the demands of its environment.

In this guide, we’ll walk you through how to do Superpave mix design step by step. We’ll also uncover the common challenges and tips to solve it to  create pavements that are built to perform.

Factors Affecting Asphalt Compaction and How to Control Them
Factors Affecting Asphalt Compaction and How to Control Them

There are plenty of factors affecting asphalt compaction. It can be the material properties and base layer conditions, the temperature outside, and even how the rollers are run.

So how do you keep compaction under control? In this article, Qualitest walks you through the key factors you need to watch out for, the right ways to test compaction both in the lab and on-site, and the best practices that help get the job done right.

The Best Way to Perform Asphalt Compaction Test: A Guide
The Best Way to Perform Asphalt Compaction Test: A Guide

How to perform asphalt compaction test begins with understanding the expectations of pavement surface and the lifespan against the stresses. Once it has been set, you can know what compaction levels it requires, which becomes your reference point during field testing.

Nuclear vs Non-Nuclear Asphalt Density Testing: What You Need to Know
Nuclear vs Non-Nuclear Asphalt Density Testing: What You Need to Know

The line between nuclear vs non-nuclear asphalt density testing still feels a little blurry, especially if you're not in the thick of fieldwork every day. Both methods aim to assess how well asphalt is compacted, but they use completely different technologies and principles to get the job done.

Asphalt Rice Test: How It’s Done
Asphalt Rice Test: How It’s Done

How to Perform the Rice Test for Asphalt — The heavy mix of asphalt, to be exact, isn’t just made up of the material itself but also contains air bubbles. These air voids can affect the asphalt’s strength and durability. In short, they play a big role in defining the overall quality of the material.

To help you better understand how the rice test works in asphalt testing, read this article carefully. Qualitest will also share the recommended tips at the end. Let’s get started.

Step-by-Step to Do Marshall Mix Design for Asphalt

Knowing how to do Marshall mix design is one of the most reliable ways to develop an asphalt mix that meets both structural and surface requirements. This method offers clear insights into asphalt formulations that perform well under real-world pavement conditions.

How to Test Density of Asphalt - Methods, Equipment, and Best Practices
How to Test Density of Asphalt: Methods, Equipment, and Best Practices

Ever driven on a bumpy road and wondered what went wrong? The fact is, it’s common to pass roads like this. And the major reason often lies in the imbalance of asphalt density. Knowing how to test density of asphalt helps to avoid this and is obviously very important, especially when you’re working on a large-scale project.

Lab vs Field Asphalt Testing Tools - What You Need to Know
Lab vs Field Asphalt Testing Tools: What You Need to Know

Lab vs field asphalt testing tools are often mentioned in the same breath, yet they serve very different purposes. While both are critical in ensuring pavement quality, using them interchangeably without understanding their roles can lead to gaps in data, or worse, flawed decision-making in construction or maintenance.

Asphalt Testing - How It Improves Road Quality, Durability, and Maintenance Planning
Asphalt Testing - How It Improves Road Quality, Durability, and Maintenance Planning

Asphalt testing is the foundation of modern road quality assurance. This testing involves a series of evaluations designed to assess the physical and mechanical properties of asphalt mixtures used in road construction.

By identifying the material's strengths, weaknesses, and long-term behavior, this testing helps extend pavement lifespan, reduce maintenance costs, and improve road safety.
