ASPHALT EXPERT SYSTEM ®© FAQ:

 

 

- FUNDAMENTAL MISTAKES IN PREVAILING RATIONAL -

 

 CUMULATIVE ERROR, WHY?

 

Asphalt Mixture Represents The ‘Sum Of Errors’. Surprisingly, This ‘Fact’ Is Accepted At The Face Value And Not Much Objected.

However, Most Errors Are Man-Made. Source Of Errors Are Either Lack Of Comprehensive Knowledge And/Or Lack Of Adequate Software Tools. The Main Mistakes Are Made In The Following Areas: Selection Of Input Materials In Terms Of Eligibility And Compatibility, Mix Design, Testing, Specifications, Material Storage, Handling, And Mixing, Selection Of Equipment And Procedures, Micro-Environment Changes…

Certainly, Major Setback Is Lack Of Rational Asphalt Technology Knowledge®© In The Area Of Statistical Processing

 

There Is No Awareness Among Professionals That It Is Not Possible To Process All Relevant Parameters, In Each And Any Given Situation, Using Simple Multiplication Matrixes Computer Programs Or Even Worse A  Calculator, And Achieve Optimum Solution.

The Obvious Incapacity Of Seeing Through And Consequent Ignorance Of The Magnitude And Complexity Of Problems Inevitably Leads To Massive Simplifications And Accumulations Of Errors. 

 Inter-Relations Are Far From Being Linear In Math Terms.

Per Example, Change In Prices Of HMA Constituents Represents Complex Mathematical Surface Area.

 

We Cannot Stress Out More The Complexity Of Change Within Comprehensive Rational Asphalt Model ®© In Relation To

Numerous ‘Outside’ Influential Parameters, If Only Several Parameters Change, And How In Turn Its Performance Is Affected

 

There Is NO WAY THAT ONE Would Be Able To Come Up With An Adequate Solution And/Or Calculate It WITHOUT Asphalt Expert System ®©.

 

NO AMOUNT OF MECHANISTIC, SOPHISTICATED  ‘Guess & Trial’ TESTING COULD HELP RESEARCHERS TO UNDERSTAND BETTER COMPLEXITY OF RELATIONS BETWEEN ASPHALT COMPOSITION AND ITS PERFORMANCE AND COME CLOSER TO DEVELOPMENT OF UNIVERSALY VALID PERFORMANCE BASED SPECIFICATIONS FOR PERPETUAL PAVEMENT DESIGN BASED ON SUPERB ASPHALT MIXTURE DESIGN, UNLESS THERE ARE DEFINED RELATIONS TO KEY FUNCTIONAL CONSTITUENTS IN ASPHALT SYSTEM SUCH AS:

MAX VC SS/AS, opt VC BM/AS, opt VC FM/AS, and Physically Derived Values Such As VFA, VTM, RI, EVC FM/BM, etc.

 

 

 

Only Rational Approach To This Complex Matter Results In MAXIMUM REDUCTION Or Eventual ‘TOTAL’ ELIMINATION OF CUMULATIVE ERROR

Then CONTROL OF THE SYSTEM Would Be Real IN ANY GIVEN MOMENT FOR ANY GIVEN SET OF PARAMETERS/CONDITIONS/RESTRAINTS.

Asphalt Expert System ®© Intelligently Leads Its User To The ‘Green Zone’/ The Error Free Zone.

If Asphalt Expert System ®© Is Not Used The Appearance Of Cumulative Error Is Highly Likely.

It Really Does Not Matter If That Would Lead To Hidden Failure Or Noticed One Which Could Be Sanctioned By Non-conformity Penalties.
