Pre-Design Intelligence. Performance-Based Validation.
AIMIXDESIGN combines aggregate engineering, intelligent binder-content estimation and Balanced Mix Design validation to define technically consistent, performance-optimized asphalt mixtures.
Aggregates, binder, RAP, filler and additives.
Richness modulus, analytical BMD and volumetric boundaries.
Rutting, cracking, moisture and fatigue verification.
Volumetrics guide the design. Performance validates it.
AIMIXDESIGN is aligned with a performance-modified volumetric approach: preliminary proportions are engineered before laboratory testing, then adjusted until the selected performance criteria are satisfied.
The software identifies a rational binder-content window rather than treating one calculated value as the final optimum.
Binder content, aggregate structure, RAP, binder grade and additives can be modified according to test results.
Final mixture acceptance remains based on performance testing, specifications and professional engineering judgement.
A rational starting binder-content window.
AIMIXDESIGN combines specification requirements, richness-modulus estimation and analytical volumetric calculations to reduce the risk of starting from an under-asphalted mixture.
Specification Limits
Minimum binder-content requirements and applicable volumetric boundaries provide the first design constraint.
Richness Modulus
Binder demand is estimated from aggregate specific surface, gradation continuity, filler content, nominal size and packing behaviour.
Analytical BMD
Gmm, Gsb, target air voids, VMA and VFA conditions are used to identify a preliminary volumetrically acceptable binder content.
Engineering Design Window
The result is a technically consistent range to be tested, modified and validated through laboratory performance testing.
Binder demand adapted to the actual aggregate structure.
Traditional fixed richness-modulus approaches may not fully represent modern aggregate structures. AIMIXDESIGN adjusts the estimation according to the combined gradation and aggregate-surface characteristics.
Aggregate specific surface and filler activity
Gradation continuity and compactability
Nominal maximum aggregate size
Dense, coarse or non-standard aggregate structures
RAP, polymer-modified and warm-mix scenarios
The mixture is modified until performance is balanced.
The preliminary design is not the final answer. Laboratory results guide changes to binder content, binder grade, aggregate structure, RAP, additives and production conditions.
Rutting Resistance
Wheel Tracking, Hamburg, APA or equivalent tests verify resistance to permanent deformation.
Cracking Resistance
IDEAL-CT, CT Index or equivalent criteria verify cracking tolerance and mixture flexibility.
Moisture Susceptibility
Moisture-damage results guide the possible use of hydrated lime, liquid anti-stripping additives or mixture redesign.
Fatigue Performance
Optional fatigue testing can support high-value, heavy-traffic or structurally demanding applications.
Binder grade and mixture performance interact.
Pavement design defines the target performance level, but mix design verifies whether the selected combination of binder, RAP, aggregate structure and dosage can realistically achieve it.
AIMIXDESIGN supports comparison of alternative PG grades and binder systems when performance testing indicates excessive rutting, insufficient cracking tolerance or incompatibility with high RAP levels.
Decision support, not a substitute for laboratory testing.
AIMIXDESIGN is an engineering support and pre-optimization platform. Final acceptance remains subject to applicable agency specifications, validated laboratory testing, production verification, field performance and professional engineering judgement.
