Asphalt Testing
Service Overview
GeoStructures’ team of experienced asphalt technicians utilizes cutting-edge equipment to deliver a comprehensive range of asphalt testing services. Our testing methods ensure the highest quality and performance standards for asphalt materials used in construction projects.
Penetration (ASTM D5/AASHTO T49)
Measure the penetration depth of a standard needle into asphalt to determine its hardness and consistency.
Saybolt Viscosity (ASTM D7496/AASHTO T59-T72)
Assess the viscosity of emulsified asphalt to ensure it meets specified flow characteristics.
Sieve Test (ASTM D6930/AASHTO T59)
Perform sieve analysis to evaluate the particle size distribution in emulsified asphalt.
Residue by Evaporation (ASTM D6934/AASHTO T59)
Determine the residue left after evaporating the water from emulsified asphalt to evaluate its binder content.
Residue by Distillation (ASTM D6997/AASHTO T59)
Measure the residue from emulsified asphalt by distillation to assess the quality and quantity of the asphalt binder.
Sieve Analysis of Extracted Aggregate (ASTM D5444/AASHTO T30)
Analyze the particle size distribution of aggregate extracted from asphalt mixtures to ensure compliance with design specifications.
Quantitative Extraction of Asphalt Binder from HMA (ASTM D2172/AASHTO T164)
Extract and quantify the asphalt binder content in Hot Mix Asphalt (HMA) to verify mix proportions.
Theoretical Maximum Specific Gravity (Gmm) and Density of HMA (ASTM D2041/AASHTO T209)
Determine the theoretical maximum specific gravity and density of HMA for quality control and mix design validation.
Asphalt Content by Ignition Method (ASTM D6307/AASHTO T308/PTM 757)
Measure the asphalt content in mixtures using the ignition method to ensure proper binder proportions.
Density of Asphalt Mixture Specimens by Means of the Superpave Gyratory Compactor (ASTM D6925/AASHTO T312)
Compact asphalt mixture specimens using the Superpave Gyratory Compactor to evaluate density and air voids.
Moisture of HMA by Oven (AASHTO T329)
Determine the moisture content in HMA using oven drying methods to ensure optimal mix performance.
Core Drilling
Extract asphalt core samples from pavements to analyze in-place density and material properties.
Density of Compacted Asphalt
Determine the density of compacted asphalt to ensure longtime pavement performance.
Bulk Specific Gravity Using Coated Specimen (ASTM D1188/AASHTO T275/PTM 716)
Determine the bulk specific gravity of compacted hot mix asphalt by measuring its sample weight dry, saturated surface dry (SSD), and submerged.
