The Lagan group of companies is a privately held family-owned construction business established in 1962
by Peter Lagan. Lagan has grown from it’s original quarrying activity origins to be the major
international Specialist Contractor that exists today.
As a leading specialist contracting business founded on more than 55 years’ experience, we work
across Ireland, the UK, US and internationally undertaking infrastructure, capital and maintenance
projects through a variety of procurement routes for public and private organizations.
Since 2005, Lagan affiliated companies have successfully delivered projects both as
a Prime Contractor and as a specialized airfield paving subcontractor on civil and
military airfields. Lagan has extensive expertise in the construction of both
airfield pavement types: Hot-Mix Asphalt (HMA) and Portland Cement Concrete (PCC).
For flexible pavements such as runways, taxiways, and aprons, the FAA specifies P-401
HMA, while the Department of Defense uses UFGS 32 12 15.13 – Asphalt Paving
for Airfields. Both specifications require the use of high-quality aggregates
and asphalt binder, placed and compacted in multiple lifts to achieve the density,
strength, and smoothness necessary to withstand aircraft loading. These pavements
provide cost-effectiveness, smooth ride quality, and easier maintenance compared to
rigid systems.
For rigid pavements, the FAA requires P-501 Portland Cement Concrete, while the
military uses UFGS 32 13 14.13 – Concrete Paving for Airfields and Other Heavy-Duty
Pavements. Both standards call for the placement, finishing, and curing of
high-strength PCC slabs capable of resisting heavy and repeated aircraft wheel loads.
Designed for long-term durability and reduced maintenance, these specifications
establish stringent requirements for strength, smoothness, and service life.
The choice between HMA and PCC is typically based on project needs, expected
aircraft traffic, and environmental conditions.
