B2 INFILTRATION

"REPORT ON FUEL INFILTRATION TESTS USING RESIBLOCK SEALANT ON CONCRETE

BLOCK PAVING" Kent County Council, Engineering Services Laboratory.

Examiner P G Shrubsole
Date 19-23 September 1994
Checked I D Walsh

Introduction

of water and a variety of fuels into concrete block paving. The test method ensured that the pavement

surface as a whole, i.e. the paving blocks and the joints, was subjected to the infiltration tests.

Materials used

Concrete paving blocks	200mm x 100mm x 80mm chamfered (Greenham Concrete Products)
Bedding sand	BS6717:Pt 3:1989, Table 2 (ARC Brevmoor).
Jointing sand	BS6717:Pt 3:1989, Table 2 (ARC Brevmoor).
Infiltration liquids	a) Unleaded petrol, BS EN228 :1993
	b) Aviation fuel (AVGAS)
	c) Diesel fuel, BS EN590 :1993
	d) Water, BS 6068 :1988

Method

A test panel 600mm by 600mm was made up from blocks laid in a basket weave pattern and compacted onto the sand

bedding to achieve 30mm thickness of bedding. The joints were filled with jointing sand and the panel compacted with

a vibrating plate compactor.

The RESIBLOCK was applied, according to published recommendations.

For each test liquid a glass permeameter (140mm ID by 100mm high) was fixed to the block paving over the joints of three

adjacent blocks. The permeameter was fixed to the paving with epoxy putty and silicon RTV rubber, ensuring a complete

seal. The inside edge of the sealant was cut away to ensure the correct test area.

A 0.5 litre sample of liquid was used for each test, which is equivalent to an initial head of 35mm. This height was

considered appropriate and is more severe than is likely to occur during spillage on a service station forecourt.

Results

*Recommendations by University of Newcastle work for British Aerospace Military Aircraft Ltd.

Conclusions

The application of RESIBLOCK ensures that a concrete block pavement, laid in accordance with BS 6717 - Part III

satisfies the maximum specified infiltration rate recommended by University of Newcastle following their study for

British Aerospace Military Aircraft Ltd.

B3 SKID RESISTANCE

The application of any sealant/coating to block paving may effect the skid/slip resistance of the pavement. Therefore the effect of skid resistance was to be investigated.

Method

To measure the effect of the application of RESIBLOCK '22' on the skid resistance of concrete pavers, a portable

pendulum friction tester was used. The test results are shown in this table.

Surface Tested	Pendulum Test Result
Concrete pavers -  unsealed	75
Concrete pavers - RESIBLOCK sealed	56

Conclusions

These results indicate an initial reduction for concrete block paving of only 25% after the application of RESIBLOCK.

However even this reduction is only temporary, as thereafter weathering and abrasion by foot and vehicular traffic

rapidly re-introduces the fine surface grip of concrete block paving surface as the RESIBLOCK is abraded. With clay

pavers the SRV can actually increase after sealing.

The SRV values obtained show that after the application of RESIBLOCK, the pavers are satisfactory for vehicular or

pedestrian traffic slip resistance.

B4 ASTM/BS TESTING

Comprehensive laboratory testing was carried out to find out the tensile strength and elongation of both RESIBLOCK

SUPERIOR and RESIBLOCK '22'. A modified test method BS2782 Part 3 Method 320A rather than ASTM D2370 was

used, as it was felt that the BS tests were somewhat more rigorous and hence the resultant data was more meaningful.

The main difference between the two tests being the size of the test specimen.

In both cases the products showed excellent tensile strength, but what is more important showed exceptional elongation characteristics. At the time when this document was published the highest known elongation requirement called for in any specification was 100%.

ABRASION RESISTANCE

Concrete substrates that are particularly liable to abrasion, such as factory and warehouse floors, spillways aprons and

carriageways, will benefit greatly from a coating of RESIBLOCK over conventional types of surface hardener. Abrasion

tests on different concrete mixes have given the following test results.
