People with visual impairment (PVI) in the Philippines have always been neglected
whenever new transportation systems and infrastructure are made. This warrants better
accommodations and services for PVI, especially regarding mobility. With the introduction
of tactile pavement, a system of textured ground surface indicators is usually used to aid
visually impaired pedestrians, and researchers aim to improve the experience of PVI and
promote a PWD-friendly environment. The introduced glass fiber-reinforced concrete

tactile paving block (GFRC-TPB) was evaluated through survey, user-testing, and field-
testing to assess its effectiveness in terms of its usability and integrity. Moreover, the

properties of the subgrade were determined through the California Bearing Ratio (CBR),
the Moisture-Density Relation of Soil (MDR), and the Field Density Test by Sand Cone
Method (FDT). A survey involving 15 blind participants was conducted, with baseline and
endline data analyzed using the Paired T-test. For user testing, the time it took the same 15
participants to navigate a path paved with GFRC-TPBs prior to and after its installation
was recorded and analyzed using Paired T-test. For field testing, the rutting behavior of the
pavement was observed as it withstands 500 passes by a lightweight vehicle. The elevation

difference was recorded every 50 passes. The subgrade passed the requirements of the on-
site and laboratory tests. GFRC-TPB was shown to impact the mobility and orientation of

the PVI positively. This is also supported by the evident improvement in their navigation
time from the user testing. The strength and integrity of GFRC-TPB were demonstrated
and proved optimal, as it displayed minimal rutting and exhibited no cracks after the field
testing.
