The asphalt compaction is the process that creates the mixture of asphalt into a strong and durable pavement. Being one of the most important stages of asphalt paving, as it is necessary to build a safe and uniform pavement.
What is Compression?
Compaction is a process consisting of the application of loads through the passage of compactor rollers or vibrating plates immediately after the application of the asphalt mass. This step helps reduce voids and increases the density of the asphalt, making it firmer and more resistant to wear.
Importance of Compaction in Paving
When there is proper compaction, we ensure safety, performance, and a longer lifespan of the road. But, without proper compaction, the pavement loses quality, becoming susceptible to infiltrations and wear.
Types of compression
The static and dynamic compaction methods are the most commonly used. In static compaction, the weight of the rollers is used to increase the pavement density. In dynamics, vibratory rollers are used to assist in the settling of the material. The choice of method should depend on the type of soil, project specifications, and pavement characteristics.
Methods of Compaction Assessment
After the compaction process, tests and measurements are conducted to verify if the density and degree of compaction have reached the levels required by technical standards, such as the NORMA DNIT 031/2024 – ES, which we will see next.
Standard and Compaction Guidelines
The NORMA DNIT 031/2024 – ESis an important guide to ensure the quality of asphalt pavement works in Brazil. It defines which materials should be used, such as the different types of aggregates and petroleum asphalt cement (PAC), specifying criteria such as durability and the correct particle proportion. It also provides guidance on the ideal equipment and processes, from the production of the mixture to transportation, surface preparation, binder application, and compaction. Furthermore, the standard provides rules for quality control at all stages, with inspection methods that ensure the pavement is executed correctly, safely, and durably.
The commitment of Rockefeller Ambiental
At Rockefeller Ambiental, we are committed to strictly adhering to technical standards and aim to deliver resilient and durable pavements, always prioritizing the quality of the pavement and the environment.
