What Is Mastic Asphalt?

Typically consisting of aggregates and bitumen, asphalt is a regular sight throughout the UK due to its use for paving and roofs. And while many of us are well aware of what asphalt is, the same can’t always be said for mastic asphalt

So, to help answer several common questions, we have put together a What is Mastic Asphalt? guide to hopefully provide some clarity. 

What is Mastic Asphalt?

A centuries-old material, mastic asphalt consists of a mix of graded limestone aggregate and bitumen. As a result, mastic asphalt is often much softer than its regular alternative, which makes it ideal in colder temperatures where laying heated asphalt often presents challenges. 

How Does Mastic Asphalt Work

The mastic asphalt process is relatively straightforward for a qualified professional, with the asphalt heated before being spread and pressed across the relevant area. As the mastic asphalt cools, it also hardens to create a durable bond. 

The Benefits of Mastic Asphalt

Mastic asphalt has long had a reputation as a popular choice for a variety of purposes, mainly due to its many advantages. 

Benefits of mastic asphalt include:

  • Quick to lay – Applied in a single layer rather than in stages, mastic asphalt‘s seamless, in-one application ensures a fast and efficient process. 
  • Long lasting qualities – Typically lasting around 50 to 60 years, mastic asphalt’s hardwearing and durable nature ensures an ideal choice for a long-lasting solution.
  • Versatile – Whether for paving, roofing or various other surfaces, mastic asphalt can suit multiple purposes, making it a versatile option for all manner of projects. 
  • Waterproof – Mastic asphalt’s water-resistant nature makes it a particularly suitable solution for roofs, as it can help significantly decrease the risk of leaks. 
  • Thermal stability – Resistant to both hot and cold extremes, mastic asphalt is suitable for a range of outdoor environments.
