AASHTO M288
Full Name
AASHTO M288 – Standard Specification for Geosynthetic Specification for Highway Applications
Scope
AASHTO M288 is a standard specification that outlines the requirements for geosynthetics used in various highway construction applications. Geosynthetics are polymeric materials used to enhance the performance and longevity of transportation infrastructure. These materials include geotextiles, geogrids, geonets, geomembranes, and geocomposites, each designed to fulfill specific functions within a highway project.
Key aspects of AASHTO M288:
- Scope: the specification covers a wide range of geosynthetic applications in highway construction, including:
- Subsurface drainage: geotextiles and geocomposites used to filter and drain water within the pavement structure, preventing water-related damage and improving stability.
- Separation: geotextiles used to separate different soil layers, preventing the intermixing of materials and maintaining the integrity of the pavement structure.
- Stabilization: geogrids and geotextiles used to reinforce soil layers, increasing their load-bearing capacity and improving stability.
- Erosion control: geotextiles and geonets used to prevent soil erosion on slopes and embankments.
- Paving: geotextiles and geocomposites used in asphalt overlays to improve crack resistance and reduce reflective cracking.
- Performance requirements: AASHTO M288 specifies the performance requirements for each type of geosynthetic and application, ensuring that they meet the intended purpose and contribute to the longevity and performance of the highway infrastructure.
- Testing methods: the standard outlines standardized test procedures for evaluating the physical, mechanical, and hydraulic properties of geosynthetics.
Significance of AASHTO M288:
- Improved performance: geosynthetics play a crucial role in enhancing the performance, durability, and longevity of highway infrastructure. By adhering to AASHTO M288, engineers and contractors can ensure the proper selection and use of geosynthetics to achieve optimal results.
- Cost-effectiveness: geosynthetics often offer cost-effective solutions for addressing various challenges in highway construction, such as poor soil conditions, erosion control, and pavement reinforcement.
- Standardized testing: AASHTO M288 provides standardized test methods for evaluating geosynthetics, ensuring reliable and comparable results for quality control and performance assessment.
