Bituminous Mixtures

What we offer

Bituminous mixture testing we offer at XAIS-PTS includes:

Preparation of samples for determining binder content, water content and grading to BS EN 12697-28:2001.
Soluble binder content by difference, using bottle rotation machine and pressure filter to BS EN 12697-1:2012
Soluble binder content by recovery, using bottle rotation machine, bucket centrifuge type 1 and volume calculation to BS EN 12697-1:2012
Particle size distribution to BS EN 12697-2:2015.
Bulk Density BS EN 12697-6:2012 (Dry, SSD, Sealed or by dimensions) of a core and Maximum Density to BS EN 12697-5:2009 from which we can find the voids content in accordance with BS EN 12697-8:2003 of a core sample. This is highly useful in checking compaction compliance and a major requirement in utility coring compliance.
Percentage of the voids in the mineral aggregate filled with binder (vfb) to BS EN 12697-8:2003.
Voids content in the mineral aggregate (vma) BS EN 12697-8:2003.

We offer the ability to measure the rut resistance of the Asphalt Surface course and Binder course for R&D purposes and quality control. These tests are in line with BS EN 12697-22:2003 Procedure A and B. We also still provide the old BS Wheel tracking rate to BS598-110:1998 for comparison purposes. We have two Coopers small wheel trackers, which means we can turn around samples quickly.

Characteristic Tests

We have three of the latest and greatest Cooper Research Technologies Nottingham Asphalt testers that can perform a range of characteristic tests on asphalt mixtures. These tests include; two methods of fatigue testing; indirect tensile test on cylindrical shaped specimens in accordance with BS EN 12697-24:2004 & fatigue characteristics using indirect tensile fatigue Documented In-House Method: C6 ITFT Issue 5, 24/08/11 based on BS DD ABF: 1995.

Stiffness Modulus tests – test applying indirect tension to cylindrical specimens (IT-CY) in accordance with BS EN 12697-26:2004 Annex C. Determination of the dimensions of a bituminous sample to BS EN 12697-29:2002.

We also offer the old withdrawn standard (but still useful in certain applications).

Resistance to permanent deformation – unconfined dynamic loading under vacuum (VRLAT) to DD226:1996 where larger cores cannot be taken gives the chance to give an indication of rut susceptibility.

We have just acquired 3 cyclic compression setups in order to perform the cyclic compression test Method B in line with EN 12697-25:2016. This is a new test and is now being asked for more frequently, and replaces the old withdrawn vRLAT standard.

We have the ability to mix Asphalt in one of our 3 mixers in a range of sizes from 2Kg up to 75Kg in accordance with BS EN 12697-35:2004. We can compact materials either by Vibratory compaction, Gyratory compaction (none UKAS) and 305mm x 305mm slab compaction (none UKAS).

If you have any queries or requests for bituminous mixture tests then please contact the lab and we will be happy to help.

Testimonials

Trusted by the Industry

Pavement Testing Services provided us with surveys working under an exceptionally tight time frame, the team were extremely accommodating and helpful throughout the duration of the contract.

Communication was prompt and most importantly issues raised were dealt with professionally and swiftly. I would have no hesitation in recommending PTS.

Jeanette Shiel

Senior Engineering Technician – Bury Council

PTS are an all-round, highly professional company and have worked with Highways England for a number of years. Working openly and collaboratively on all Highways England projects they are continually striving to improve. Their ability to deliver consistently at such a high level should be recognised and I would have no reservations in recommending PTS.

Graeme Watt

Asset Needs Manager Highways England

PTS carried out our SCRIM Survey this year, the data they have provided loaded easily into our UKPMS. The post survey customer service that we received was excellent.

John Peel

Senior Engineer Tameside Council

We use Pavement Testing Services after being procured through the Greater Manchester asset management group. Communication and quality of work throughout the full process was excellent and any issues raised where resolved in a timely manner. I would have no hesitation in recommending PTS.

Michael Aiken

Technician/Snr Tech/Asst Engr Rochdale Borough Council

Derbyshire have worked with Pavement Testing Services for four years and in that time they have provided good survey data and responded quickly to queries.

The staff are friendly and helpful and we are very happy with the service.

Julie Price

Project Engineer, Derbyshire County Council

PTS undertook pavement surveys on the A12 Chelmsford to A120 widening scheme between Dec 2019 and June 2020. PTS provided high quality condition data promptly and efficiently and the team responded quickly and effectively to all enquiries. I have no hesitation in recommending the expertise of PTS as an accommodating, efficient and very professional team.

Andrew Davies

Civil Engineer, A12 to A120 widening scheme, Costain

PTS offer a wealth of experience in carrying out both visual and mechanical highway condition surveys and have a sound understanding of the services required to meet WSCC’s own policies and best practice procedures. PTS provide excellent customer focus and adapt to any changes to requests at short notice. PTS have always kept to tight deadlines and deliver a very high standard of performance for which I have no hesitation in recommending them for future highway condition survey contracts of this kind.

David Kitt

Highway Network and Data Information Manager, West Sussex County Council

PTS have provided the SCRIM, Griptester, Deflectograph and SCANNER on our contract for the past 4 years. During this time both the level of service and condition data we have received from PTS has been of a high quality as well as being provided in a prompt and efficient manner. PTS have always been willing and able to provide additional services when requested.

Steve Wibberley

Asset Manager (Network) Amey

PTS have worked with Medway Council for a number of years, and have always provided a professional service when undertaking our Highway Condition Assessments. They have continuously met tight deadlines when required, and have striven to improve the way in which our highway assessments are reported. Staff have always been helpful and approachable, and I would therefore happily recommend PTS.
